The real question which you should ask yourself is why you want to keep the kernel and the user processes on separate CPUs. What is it to you which CPU the scheduler places processes? Firwall happens within the kernel but so do all the system calls that the other processes issue. AFAIK, the kernel stays on one CPU and is why MP doesn't help firewall performance. If your firewall can't keep up and other CPUs are idle, then you need a more powerful CPU or a separate box just for the firewall. Doug.
